I've been trying to figure out for a while now how to change the frequency of the types of planets which spawn. It seems like theres just too many useful planets and not enough useless parts in space in random maps. I would to like to adjust this primarily so that colonizable planets are far more needed.

Mainly because during large games, I'll have so many planets to the point where I don't even have to worry about what I want to build. This adjustment would of course mean more micromangement, but at the same time I think it would be more unique due to the types of choices which will have to be made due to limited resources/space.
